| C. The Verbs of Motion |
The verbs of motion, or more specifically, of going and carrying, exhibit a further distinction within the imperfective category. While the majority of verbs have only one imperfective form to describe two separate types of action (i.e., action in progress and habitual action), the verbs of motion have two imperfective forms which distinguish these separate meanings. The determinate imperfective describes an action (going or carrying) in progress and in a specific direction. The indeterminate imperfective describes habitual actions (going or carrying) and actions in which no specific direction is involved.
For instance, the two imperfective forms of 'to go by one's own means' are the indeterminate ходить and the determinate идти:
Профессор ходит (ходил) в лабораторию каждый день. > The professor goes (went) to the laboratory every day.
Профессор идёт (шёл, когда я его видела) в лабораторию. > The professor is going (was going, when I saw him) to the laboratory.
The conjugations of these two verbs are as follows:
| ходить (indeterminate imperfective), 'to go by one's own means' | |||
| | хожу ходишь ходит | ходим ходите ходят | |
| | ходил, ходила, ходило, ходили | ||
| идти (determinate imperfective), 'to go by one's own means' | |||
| | иду идёшь идёт | идём идёте идут | |
| | шёл, шла, шло, шли | ||
| Note the past tense of идти: он шёл, она шла, оно шло, они шли. | |||
The perfective of the verb 'to go by one's own means' is пойти:
